Re: OT: Why is a Pomona Dual Banana Plug Shorting Bar Polarized

From my experience as a design engineer working with contract assembly houses, not specifying an orientation for insertion of a given component will generate lots of questions. I'm guessing Pomona marks one end so orientation can be specified avoiding the delay of these questions. I have had to spec this for NP caps, smd resistors (orient so the printed ID is in a given direction), etc.

I just noticed they have the usual tab sticking out on one side with the abbreviation GND on it. Does Pomona know something about shorting bars that I don't? Was I using them wrong half of the time if I wasn't paying attention to their orientation? Does anyone pay attention to the polarity of a shorting bar? Another thing: According to Mouser the Yaego 0 ohm resistors they sell are specified at only 1%. How do they know? Finally: Why are the buttons on the cash machine at the drive up window of a bank in Braille? Dennis Tillman W7PF
